Prepare to be amazed: a 13-year-old is about to make history in the world of swimming. Yu Zidi, a name you’ll want to remember, is set to become the youngest swimmer ever to rank in the global top 10 of an event by the end of the year. But here's where it gets even more astonishing: she’s currently sitting at #2 in the 200-meter butterfly, and she’s just getting started. This isn’t just a story about breaking records—it’s about redefining what’s possible at such a young age.
Yu Zidi first grabbed headlines at the 2025 World Aquatics Championships when, at just 12 years old, she finished 4th in the women’s 200 butterfly, 200 IM, and 400 IM. But that’s not all—she also became the youngest swimmer in history to win a medal at this prestigious event, taking home bronze in the 4×200 freestyle relay. Fast forward to the Chinese National Games, where she’s continued to dominate. With a time of 2:07.41 in the 200 IM, she shattered the Asian Record previously held by Ye Shiwen—a record set in 2012, before Yu was even born. This performance not only secured her a spot as the #2 swimmer in the world behind Summer McIntosh but also cemented her place in swimming history.
And this is the part most people miss: Yu Zidi isn’t just finishing the year in the top 10—she’s likely to end it as #2 in the 200 IM, 4th in the 400 IM, and 7th in the 200 butterfly. At 13 years and 76 days old, she’s achieving feats that most swimmers can only dream of. But what does this mean for the future of swimming? Is she the next Michael Phelps, or is her success a one-time phenomenon? Let’s dive deeper.
The table below highlights the youngest female swimmers to reach world-ranking positions #1 through #100 since 2000. Spoiler alert: Yu Zidi’s name appears multiple times, and it’s not just her—Chinese swimmers dominate the list, with the exception of Japan’s Runa Imai and Italy’s Benedetta Pilato.

On the men’s side, Michael Phelps holds the title of the youngest male swimmer to reach #1 since 2000, achieving this feat in the 200 butterfly at just 16 years old. But Hungary’s Daniel Gyurta deserves a shoutout too—he’s the youngest swimmer since 2000 to finish a season in the top 100, doing so at 13 years old in 2002.
Here’s the men’s table for comparison:
| Rank | Year | Event | Swimmer | Time | Age |
|------|------|---------------|--------------------|---------|----------------|
| 1 | 2001 | 200 fly | Michael Phelps (USA)| 1:54.58 | 16 years, 184 days |
